HERBERT S. SMITH, OF NET YORK, N. Y., ASSIGNOR OF ONE-HALF TO CHARLES DEXTER ALLEN, OF NET YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 767,449, dated August 167 1904.

T all whom t may concern:

Be it known that I, HERBERT S. SMITH, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Envelops, of which the following is a specification.

This invention pertains to envelops or bags, and more particularly to the manner of closing them through the instrumentality of specially-devised forms of flaps or flies.

Among the apparent objects those calculated to effect-absolute closure are important, also to provide an inexpensive, durable, and efficient article of manufacture.

Referring to the drawings `forming a. part of this specification, Figure l illustrates perspectively the envelop or bag, one of the iiaps of which is lengthened, and the view is also broken away to show the manner of closure. Figs. 2' and 3, respectively, indicate the manner of closing with the lengthened flaps or flies. Fig. 4 illustrates an envelop with its laps extended still farther than those shown in the previous figures, and the closure is partly broken away to show the arrangement. Fig. 5 illustrates an envelop with the iiaps or iies suitably creased, as seen in Fig. 6, and the view is broken away to show the relation of the flaps or fiies when closed. Fig. 7 illustrates the flaps or iies provided with a tongue formed from the material of the bag and slit, whereby 'the closure maybe interlocked, as seen in Fig. 8.

Similar characters of reference indicate like parts in all the views.

The envelop or bag will be generally indicated by 1 and which may open at any desirable point. In the present case such opening may be at the end, as 2.

The open end of the envelop may be provided with flaps 3 and 4, respectively.

As to the construction of the envelop or bag 1, this may be of any suitable type, it being shown merely in illustration that said envelop may be pasted along' its edges 5 and 6 or in any other suitable manner.

The flaps, which in the present instance may be generally designated by 3 and 4, may be of any suitable construction. As shown,

they may consist of two extensions 7 and 8 on the walls of the envelop or bag. Again, the iiaps 7 and 8, respectively, maybe further lengthened, and one may be of greater length than 12, the latter, if so desired, being provided with'one crease, while its mate may be provided with two such or similar creases, when the eXtreme fly 13 of the flap 12 may be overturned into place against the fly 14 and then the operation repeated, overturning the fly 15 against the fly 16, whereby to make a reinforced closure, as seen at 17 of Fig. 4.

The arrangement shown in Figs; 5 and 6 is similar to that shown in Figs. 1, 2, and 3. In this case, however, theflies 25, 26, 27, and 28, respectively, may each be the same length, and being suitably creased, as shown, the closure may be effected as illustrated in Figs. 5 and 6. In the iiies 26 or in any of the others aforementioned there may be provided a slit 29, and one of the flies, as 28, may be suitably cut to form a tongue 30, which may be introduced into the former, as seen in Fig. 8, or both iies may be cut identically alike, so as to fold or close interchangeably atwill.

Thus it will be seen that there is provided an envelop or bag having two or more flaps adapted to close into each other and form a substantial closure. Also by such structure and arrangement the use of gum or adhesives for closing purposes is rendered unnecessary, although the same may be employed, if desired. Furthermore, the closure construction may, if desired, be placed on any or as many ends of the."v envelop as necessary or desired. It will also be observed that such a closure as is provided will have an accordion effect, giving it displacement to accommodate the thickness of contents without straining or breaking the closure.

It will be seen that I provide an envelop or bag having at its opening a pair or plurality of interlocking or interfolding flaps whereby to provide an absolute closure.

It might be said that each flap of the closure IOO 2. An envelop or bag', from the material ot' the body portion ot' which extend two flaps lor forming' the closure, euch flap comprising' two flies ot' equal length so Constructed or l'ormed as to be interchangeable for insertion into the bag' to formsaid Closure. a slit in one ot the flies, and a tongue 'formed on another whereby the interfolding [lies may be looked.

Signed at Nos. 9 to 15 Murray street, New York, N. Y., this 5th day of November, 1903.

HERBERT S. SMITH.
